hahahaha this is hella cool do you still have the link were you got your vector thingy?
your smuding is getting really nice man, the only problem i have is the car looks plain, and there isn't really enough detail in this piece to make it look interesting after a while.
Maybe look at some tutorials on how to put body work on a car, and just add some interesting patterns to it.
What shape dynamics do you use generally while smuding, or effect etc?
